FreeBSD 7.1 crashing on shutdown, halt etc.

[Jeffrey Racine]

Hi.

My system is crashing when I log out (using gdm). I had posted to gnome but was 
just advised to post to x11, posted to x11 and was told this is a kernel bug. 
Many thanks for any all of your assistance. Backtrace is provided below.

Some system info:
